Definitions
- the present invention relates to a process for the preparation of a special hydroxy compound by decarboxylation of a specific carboxylic acid compound or a salt of this carboxylic acid compound, a process for the preparation of a diaryl carbonate, a bisphenol or a polycarbonate, a diaryl carbonate or bisphenol, a polycarbonate and a process for adjusting the isotope ratio from C14 to C12 in a polymer.
- Phenols with different substitution patterns on aromatics are the starting compounds for different monomers and thus also for the resulting polymers.
- the production of such phenols from renewable raw materials is a great challenge.
- One possibility for the production of bio-based phenols is the direct fermentation of sugars, such as described in WO 2014/076113 A1.
- phenol is toxic to the microorganism described there and also the removal from the aqueous fermentation broth is expensive.
- Hydroxybenzoic acids such as 4-hydroxybenzoic acid, 2-hydroxybenzoic acid and 3-hydroxybenzoic acid can also be produced fermentatively from sugars. Since they are generally less toxic to the microorganisms used, higher yields can normally be achieved compared to phenol.
- Hydroxybenzoic acids can be crystallized and separated from the fermentation broth. A subsequent decarboxylation of 4-hydroxybenzoic acid to phenol has also already been described.
- JP 2016-23136 A describes the reaction using a heterogeneous catalyst in water as a solvent.
- A.S. Lisitsyn / Applied Catalysis A: General 332; 2007 (166-170) describes decarboxylation in diphenyl ether using a copper catalyst.
- L.J. Goossen et al. describe in ChemCatChem 2010, 2, 430-442 the decarboxylation using a silver or copper catalyst in NMP as a solvent. Also in Dalton Transactions (24), 4683-4688; In 2009 the decarboxylation in toluene is described.
- the present invention was therefore based on the object of providing a process for the preparation of special hydroxy compounds of the formula (I) by decarboxylation of a carboxylic acid compound of the formula (II) or a corresponding salt of this carboxylic acid compound of the formula (II), which has at least one disadvantage of the state of the art Technology improved.
- the object of the present invention was to provide a process which gives the hydroxy compound of the formula (I) in high purity.
- the hydroxy compound of the formula (I) obtained is said to be particularly suitable for use as a starting material for further chemical compounds.
- the hydroxy compound of the formula (I) should be provided by a process in which the workup of the product is as inexpensive as possible and is therefore preferably inexpensive and environmentally friendly. It was desirable that a heterogeneous catalyst be used, since this already makes it easier to separate the catalyst from the hydroxy compound of the formula (I).
- At least one, preferably all of the above-mentioned objects have been achieved by the present invention. It has surprisingly been found that the decarboxylation of a carboxylic acid compound of the formula (II) or a corresponding salt of this carboxylic acid compound of the formula (II) can be carried out effectively using a heterogeneous catalyst in a hydroxy compound of the formula (I) as a solvent. The yield of the desired hydroxy compound of the formula (I) is preferably even higher than under the conditions described in the prior art.
- the use of at least one hydroxy compound of the formula (I) as a solvent during the reaction of the decarboxylation has the particular advantage that a reaction mixture is obtained which can be used directly as a starting material for further chemical reactions after the catalyst has been removed without complicated work-up. On the one hand, this is because the reaction is almost complete. Secondly, it is not necessary to separate the solvent.
- the process can particularly preferably be designed such that the solvent used corresponds to the desired hydroxy compound of the formula (I) to be prepared. As a result, an almost pure hydroxy compound of the formula (I) is obtained after complete decarboxylation and separation of the catalyst.

- the case is thus excluded in which the hydroxy compound of the formula (I) forms as the target product in situ and then at some point a molar deficit of the carboxylic acid compound of the formula (II) or the salt of the carboxylic acid compound of the formula (II) is formed, because at least one hydroxy compound of the formula (I) must also be present from the start of the decarboxylation.
- the carboxylic acid compound of the formula (II) or the salt of the carboxylic acid compound of the formula (II) is thus preferably soluble in the at least one hydroxy compound of the formula (I) which is present in the stoichiometric excess of the carboxylic acid compound of the formula (II) in the entire reaction of the decarboxylation is.
